Fig. 5 is a perspective view of a ceiling plate embodied in my invention.

As here embodied my improved machine comprises a platform 10, mounted on the rollers 11. The platform 10, has attached thereto, flanged members 12, adapted to guide the rollers 13, attached to the frame work 14. The above described construction being such as will permit the platform 10 to be pushed or pulled in one direction, and which will permit the frame work 14, to be pushed or pulled on the platform 10, in a direction at right angles to the said platform The frame work 14, comprises a plurality of upright members and suitable cross members 15, so as to provide a suitable structure or supporting means. The electric motor 16, is` of ordinary construction, and 1s mounted on the base member 17, of the frame work 14. v The motor 16 is operatively connected by means of suitable electric wires to any convenient source of electric current, and to the switch 16 mounted on the upright member 14 of the said frame work. The belt 18 is extended over a pulley attached to the armature shaft of the motor 16, and over a pulley operatively attached to a. speed reduction device 19, comprising the usual reduction gears. The belt 20 is extended over a pulley operatively attached to the speed reduction device 19 and over a pulley 21 attached to the shaft 22 rotatively mounted in brackets attachedto the cross members 15. The drum 23 is attached to the shaft 22.

The wall box `24 is provided with an open top and side and has hinged thereto at its top a plaster' member 25, having its lower free edge 26 projecting somewhat beyond the wall box 24. The cam 27 is pivotally Y mounted on the side of the wall box 24, and

has attached thereto a lever 28. Theflexible member 29, a cord or the like, is attached to the lever 28, and is extended downwardly therefrom. The wall box 24, has attached thereto plate members 30. The rollers 31 are rotatively mounted on shafts carried by the pla-te members 30. The plate members 30, are provided with extended members adapted to engage the upright members 32, of the supplementary frame work. The rollers 30 being in contact with one surface of the upright members 32. The above described construction being such as will permit the wall box 24 to be slidabl mounted on the said supplementary fiame. The said'supplementary frame comprises the upright members 32, and the cross members '33, attached thereto. The supplementary frame is attached by bolts, screws, or `the like, to the above mentioned frame work, so as to be readily and easily removed therefrom. T he brace members 34, are similarly attached thereto, for the same purpose. The flexible member 36, is attached, as at 37, to the top cross member 35,` and is extended over the pulley 38 rotatively mounted in a bracket attached to the said cross member 35. The flexible member 36, is extended downwardly and over the pulley 39, rotatively mounted in a bracket attached to the wall box 24. The fiexible member 36, is extended'V upwardly from the pulley 39, over the pulley 40, rotatively mounted in a bracket attached to the cross member 35. `The flexible member 36, is extended from Vthe pulley 40, over the above mentioned drum 23, and is wound around the drum 23 and extended therefrom, having its free extremity within close proximity to the platform 10. The above described construction being such as will permit the wall box 24 to be slidably raised on the upright members 32, by theelectrio motor 16, when the free extremity of the fiexible member 36 is pulled tightly. The plaster member 25, is adapted to hold plaster or the like, which is spread on the wall of a room, the side of a house, or any vertical surface to be plastered, when the wall box 24 is slidably raised as above set forth. It being understood that the plaster board 25 may be relatively hinged inwardly or outwardly, as may be desired by manual manipulation oi the tlexible member 29, So as to fauiliate 'the spreadingl oit the plaster' on the said vertical surface. ltbeiin'g understood that the wall box 24,'niay be flowered, when the tree extremity olf the iiexible member 36 is released, or loosened. The board iiiay be raised and plaster manually placed in the box 24.

A secondary frame 43 is disposed in substantially vertical vposition on the main frame and is adapted to be raised and lowered in a vertical plane relative to Jthe main traine. The secondary frame 43 comprises side u'ienibers 43 which are provided with grooves or channels in which upright supports i4' of the main trame are disposed. It should be understood that there are two such side members 43 which are slidably mounted on opposite upright supports of the main frame and are rigidly secured together by diagonally disposed cross members 43a. A rodv 42 is disposed across the upper end of the secondframe 43 and is provided with a pivotally mounted ceiling plate 4l which is pivota'lly attached toy said rod near its center. A shelf 44 is also attached to the secondary fraine 43 by bracketsf35, a exible member or cord 46 is attached at one end, as at 47 to a cross member 33 of the main frame and is extended downwardly therefrom around a pulley 48 attached to the bottom portion of the secondaryframe 43. It should be understood that the slidably mounted secondary :trame 43 may be raised and lowered for suitably positioning the Ceiling plate adjacent the ceiling of a buildling being worked upon by manipulation ot the rope 46 as hereinai'ter more clearly set forth. The flexible member 46, is extended upwardly from the pulley 48,V over the pulley 49, rotatively mounted in a bracket attached to the cross member' l5 of the said franie work. The 'flexible member 46, is extended' dbwnwardly from the pulley 49 over the above mentioned drum 23, and is wound around the drum 23, and extended tliereirom, having its free extremity within close proximity to the platform l0. The above described construction being suehas w-ill permit the secondary fra-me work 43, and the-ceiling plate 4l to be slidably raised, by the electric motor 16, whenA the free extremity of the [flexible member 46 is pulled tightly.

The ltension springs 50 and 51, are attached to the ceiling vplate 4l, at or near the opposite extremities thereof, and are adapted to be attached' to the secondary frame work' 43. The latter described construction being such as will permit the ceiling plate' an upwardly extended angular position. The above described construction beingsuch as will permit plaster' manually placed on vt he ceiling plate 41, to be spread on the ceiling oi a room, or on a similar horizontal surface, vwhen the ceiling plate 4l, is raised 'the required height, and when my improved ymachine is pushed or rolled along the floor or ground.

In Fig. 4 of the acconipanying.drawing, I have shown the above described supplenientary frame work, provided with `an extended niember comprising upright members 52, adapted to slidably engage the said upright members 32. Thevupright members 52 having formed therein elongated slots" 53, adapted to receive the threaded members 54, are tliereadedly attached kto the upright members 32, as a means of holding the above mentioned extended member in any desired extended position above the said supplementary frame work, as may be-required to acconinviodate walls having a high ceiling.k I have also provided a telescopic brace member comprising a i'od 55, pivotally attached, at at 56, to the; upright member 52. The

tubular. member 57 is adapted to slidably engage the rod 55. The tubular member 57 is pivotally attached, as at 58, to the cross member l5 of the said fname work. The threaded member 591-is threadedly attached` to the rod 55, and is adapted to engage in an elongated slot 66l formed -in the tubular inember 57, asa means Vof holding the telescopic brace member in any desired extended posi- Sie tion, so as to securely hold the said upright 1 members 52 in place. l
